Emotion Navigation via EEG-fMRI Mapping in Human-Centric Lighting

The patent creates a mapping relationship between EEG brainwave patterns and fMRI BOLD contrast responses by having subjects experience multiple emotions while measured by both systems. This allows the complex fMRI data to be copied and represented through simpler, more commercially viable EEG measurements, enabling emotion determination without requiring expensive fMRI equipment.

The patent introduces EEG as an intermediary measurement tool that bridges the gap between the highly accurate but complex fMRI system and practical commercial applications. By establishing a correlation model where EEG patterns serve as proxies for fMRI BOLD responses, the system achieves comparable emotion determination accuracy through a simpler, more affordable intermediary measurement approach.

The patent performs preliminary calibration by having each subject experience multiple emotions while their EEG patterns are recorded and mapped to corresponding fMRI BOLD responses in advance. This pre-established mapping relationship accounts for individual variations in brainwave patterns, allowing the system to reliably determine emotions for each individual based on their unique calibration data rather than relying on generic EEG-emotion correlations.

The patent transforms the raw EEG brainwave parameters into calibrated emotion-indicating parameters through the established mapping relationship. By changing the interpretation parameters from generic brainwave patterns to individualized, fMRI-calibrated patterns, the system maintains reliability across different individuals while using the simpler EEG measurement approach.
